[0021] When it is necessary to test the plant specimens, start the stepper motor 13 and the electric heating plate 5, so that the output end of the stepper motor 13 drives the transmission tube 16 to rotate through the driving shaft 15, so that the transmission tube 16 can drive the second friction disk 17 to rotate, and at the same time, the heat generated by the heating plate 5 will be transferred to the heat conducting plate 4, so that the heat conducting plate 4 can subsequently cooperate with the absorbent cotton belt 3 to iron the leaf specimens, remove excess moisture on the surface of the leaf specimens, and flatten the leaves, which is helpful to clearly observe the shape, veins, edges and other details of the leaves during the detection process using the detector 10.

[0022] In this embodiment, the driving mechanism includes a mounting plate 12 fixedly mounted on the outer surface of one side of the box body 1, a stepper motor 13 is fixedly mounted on the outer surface of the mounting plate 12, the output end of the stepper motor 13 passes through the outer surface of the mounting plate 12 and is fixedly mounted with a drive shaft 15, the outer surface of the drive shaft 15 is sleeved with a transmission tube 16, the transmission tube 16 and the drive shaft 15 are installed through a spline transmission, a second friction disc 17 is fixedly mounted on one end of the transmission tube 16 close to the box body 1, and a first friction disc 14 is fixedly mounted on the rotation center of one of the rollers 2 close to the second friction disc 17, and the first friction disc 14 The second friction disc 17 is arranged on the same axis. A temperature monitoring mechanism is installed between the two heat conducting plates 4 in the two sets of ironing mechanisms. The temperature monitoring mechanism includes a bellows 6 embedded in the two heat conducting plates 4. A piston tube 7 is fixedly installed on the outer surface of the box body 1. A baffle is fixedly installed on the end of the piston tube 7 away from the box body 1. The two bellows 6 are connected to the inside of the piston tube 7. The inside of the piston tube 7 and the two bellows 6 are filled with mercury. A movable plug 23 is slidably installed inside the piston tube 7. A piston rod 24 is fixedly installed on the outer surface of the movable plug 23 away from the box body 1. The piston rod 24 is fixedly installed on the outer surface of the movable plug 23 away from the box body 1. 4 penetrates the outer surface of the baffle and is slidably installed therewith, a toggle assembly is installed between the piston rod 24 and the transmission tube 16, and the toggle assembly includes a fixing frame 27 fixedly installed on the outer surface of the box body 1, and a rotating rod 28 is rotatably installed on the outer surface of the fixing frame 27. A guide rod 25 is fixedly installed on the outer surface of the piston rod 24 away from the movable plug 23, and a rectangular opening is penetrated on the outer surface of the guide rod 25 near the piston tube 7 for the piston rod 24 to pass through, and a first guide groove 30 matching the guide rod 25 is penetrated on the upper surface of the rotating rod 28 near the piston rod 24. The guide rod 25 and the first guide groove 30 are connected to each other. The inner wall is slidably installed, and the outer surface of the transmission tube 16 is sleeved with a moving ring 20. A lever 22 is fixedly installed on the outer periphery of the moving ring 20. A second guide groove 29 is penetrated through the upper surface of the rotating rod 28 near one end of the moving ring 20. The lever 22 and the inner wall of the second guide groove 29 are slidably installed. A connecting component is installed between the moving ring 20 and the second friction disk 17. The connecting component includes a connecting snap ring 19 rotatably installed on the outer surface of the second friction disk 17 near the transmission tube 16. A connecting spring 21 is fixedly installed between the connecting snap ring 19 and the moving ring 20, and the connecting spring 21 is sleeved on the outside of the transmission tube 16.

[0023] When the electric heating plate 5 heats the heat conducting plate 4, the mercury in the bellows 6 embedded in the heat conducting plate 4 will expand due to the heat, so that the expanded mercury enters the piston tube 7 to push the movable plug 23 outward, so that the movable plug 23 can push the piston rod 24 and the guide rod 25 to move outward. Since the guide rod 25 is slidably installed with the first guide groove 30 provided on the rotating rod 28, and the rotating rod 28 is rotatably installed with the outer side of the box body 1 through the fixing frame 27, the piston rod 24 can push the rotating rod 28 through the guide rod 25 and the first guide groove 30 when moving outward, so that the other end of the rotating rod 28 can push the moving ring 20 toward the direction of the first friction disk 14 through the second guide groove 29 and the lever 22. When the moving ring 20 is pushed, the connecting spring 21 and the connecting snap ring 19 will apply a thrust to the second friction disk 17, so that the second friction disk 17 and the first friction disk 17 are connected. The friction surface of a friction disk 14 is in contact, so that the second friction disk 17 can drive the corresponding roller 2 to rotate through the first friction disk 14. Since the two corresponding rollers 2 in the two sets of ironing mechanisms are installed through the meshing synchronous gears 33, the rollers 2 in the two sets of ironing mechanisms can drive the absorbent cotton belts 3 to move relative to each other. When the absorbent cotton belts 3 move, it means that the heat transfer plate 4 reaches the temperature required for ironing the leaf specimens. At this time, the leaf specimens pre-placed on the feeding platform 8 can be pushed between the two absorbent cotton belts 3, so that the moving absorbent cotton belts 3 bring the leaf specimens into the box 1. When the leaf specimens move, the heat transfer plate 4 will iron them, so that the leaf specimens can be flattened and the surface of the leaf specimens is smooth, which is helpful to clearly observe the shape, veins, edges and other details of the leaves during the detection process using the detector 10.

[0024] In this embodiment, a spacing adjustment component is installed between the piston rod 24 and the two heating plates 5, and the spacing adjustment component includes an extension rod 31 fixedly installed on the side of the heating plate 5, the extension rod 31, and the end of the extension rod 31 away from the heating plate 5 is rotatably installed with a rotating block 32, and the end of the rotating block 32 away from the extension rod 31 is rotatably installed with the outer surface of the guide rod 25, and a rectangular groove is opened through the outer surface of the box body 1 for the extension rod 31 to move up and down.

[0025] When the temperature of the heat conducting plate 4 continues to rise, the piston rod 24 drives the guide rod 25 to continue to move outward, and the guide rod 25 will push the electric heating plates 5 on the upper and lower sides away from the heat conducting plate 4 through the rotating block 32 and the extension rod 31, thereby reducing the heat transferred from the electric heating plate 5 to the heat conducting plate 4, and preventing the temperature of the heat conducting plate 4 from overheating and scalding the leaf specimens.

[0026] In this embodiment, two stripping plates 11 are symmetrically fixedly installed between the inner walls on the opposite sides of the box body 1 close to the detection platform 9, and the outer surface of the stripping plate 11 away from the detection platform 9 is in contact with the outer surface of the absorbent cotton belt 3; by the side edges of the two stripping plates 11 being in contact with the outer surface of the absorbent cotton belt 3, the stripping plates 11 can scrape off the leaf specimens adhered to the outside of the absorbent cotton belt 3, thereby preventing the leaf specimens from adhering to the absorbent cotton belt 3.

[0027] In this embodiment, a return spring 26 is sleeved on the outer surface of the piston rod 24, and the return spring 26 is arranged between the baffle and the movable plug 23; After the electric heating plate 5 stops heating, the mercury in the bellows 6 and the piston tube 7 will gradually cool and shrink, so that the return spring 26 can push the movable plug 23 to return to its original position.

[0028] In this embodiment, an annular groove 18 is provided on the outer surface of the second friction disk 17 close to the transmission tube 16, and a connecting snap ring 19 is rotatably installed on the inner wall of the annular groove 18; when the movable ring 20 pulls the connecting snap ring 19 to move through the connecting spring 21, the connecting snap ring 19 can drive the second friction disk 17 to move through the connecting snap ring 19, so that the second friction disk 17 is separated from the first friction disk 14.

[0029] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: when it is necessary to detect the plant specimen, the stepper motor 13 and the electric heating plate 5 are started, so that the output end of the stepper motor 13 drives the transmission tube 16 to rotate through the driving shaft 15, so that the transmission tube 16 can drive the second friction disk 17 to rotate, and at the same time, the heat generated by the electric heating plate 5 will be transferred to the heat conducting plate 4, so that the heat conducting plate 4 can subsequently cooperate with the absorbent cotton belt 3 to iron the leaf specimen, remove excess moisture on the surface of the leaf specimen, and flatten the leaf, which is helpful to clearly observe the shape, veins and edges of the leaf during the detection process using the detector 10; When the electric heating plate 5 heats the heat conducting plate 4, the mercury in the bellows 6 embedded in the heat conducting plate 4 will expand due to the heat, so that the expanded mercury enters the piston tube 7 to push the movable plug 23 outward, so that the movable plug 23 can push the piston rod 24 and the guide rod 25 to move outward. Since the guide rod 25 is slidably installed with the first guide groove 30 provided on the rotating rod 28, and the rotating rod 28 is rotatably installed with the outer side of the box body 1 through the fixing frame 27, the piston rod 24 can push the rotating rod 28 through the guide rod 25 and the first guide groove 30 when moving outward, so that the other end of the rotating rod 28 can push the moving ring 20 toward the direction of the first friction disk 14 through the second guide groove 29 and the lever 22. When the moving ring 20 is pushed, the connecting spring 21 and the connecting snap ring 19 will apply a thrust to the second friction disk 17, so that the second friction disk 17 and the first friction disk 17 are connected. The friction surface of a friction disc 14 is in contact, so that the second friction disc 17 can drive the corresponding roller 2 to rotate through the first friction disc 14. Since the two corresponding rollers 2 in the two sets of ironing mechanisms are installed through the meshing synchronous gears 33, the rollers 2 in the two sets of ironing mechanisms can drive the absorbent cotton belts 3 to move relatively. When the absorbent cotton belts 3 move, it means that the heat transfer plate 4 reaches the temperature required for ironing the leaf specimens. At this time, the leaf specimens pre-placed on the feeding platform 8 can be pushed between the two absorbent cotton belts 3, so that the moving absorbent cotton belts 3 bring the leaf specimens into the box 1. When the leaf specimens move, the heat transfer plate 4 will iron them, so that the leaf specimens can be flattened and the surface of the leaf specimens is flat, which is helpful to clearly observe the shape, veins, edges and other details of the leaves during the detection process using the detector 10; The ironed leaf specimens will be transmitted to the detection platform 9 so that the leaf specimens can be detected by the detector 10, and the detection information of the leaf specimens can be recorded for subsequent popular science use; When the temperature of the heat conducting plate 4 continues to rise, the piston rod 24 will continue to push the rotating rod 28 to rotate, so that the connecting spring 21 arranged on the moving ring 20 is gradually compressed, so as to prevent the rotating rod 28 from being unable to rotate and being stuck; When the piston rod 24 drives the guide rod 25 to continue to move outward, the guide rod 25 will push the electric heating plates 5 on the upper and lower sides away from the heat conducting plate 4 through the rotating block 32 and the extension rod 31, reducing the heat transferred from the electric heating plates 5 to the heat conducting plate 4, and preventing the heat conducting plate 4 from overheating and scalding the leaf specimens.

[0030] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
